I have a Q&A list with "Open All/Close All" at the top with individual open and close image buttons that toggle when clicked. That works fine.

Then follow individual Q&As, and each has its own open and close image.

If you click on "Open All/Close All" first, as soon as the page loads, and then click on the individual Q&A open/close images, all works fine. But if after page load you click on the individual Q&A open/close images, bypassing "Open All/Close All," they display the inappropriate open or close image.

//On each question click, toggle the answer.
//If you have noticed, I didn't enclose both Q&A inside one DIV.

Hmm, that wasn't it. I wonder if there's an error.

Thank you for your help, though. I'm not able to integrate your code successfully with the rest of mine. I've tried various things. Can you provide the entire script? I know that's asking a lot, but I must be making a mistake in my syntax.

Thank you for taking the time to provide this. I will try this later today and report back. In my version, I toggle the Open All/Close All feature. It's a cleaner look and easier to use, since you don't have to move your mouse.
